If one were to conduct an informal survey of offices, restaurants, retail shops and other places of employment today, I would have to assume that productivity on the day is dragging at about a quarter the normal rate. After all, we're just now wrapping up The Best Party Weekend Of The Year, and it looks like between epic house parties, bar blowouts and End Of Days Boogies, it was legendary. And that's before we even get into Haunted Mansion, HARD's annual two-day electronic throwdown.

See how L.A. raged on for HARD Halloween with Skrillex, Major Lazer and Soulwax.

But why take my word for it when you could check out the pictures for yourself?
